At my local (kosher, Ashkenazi) butcher, one of the cuts of beef they sell is kulkie, or kolichel/kalichl. It's a tough, lean cut with copious connective tissue which is great for stewing. However, I haven't the faintest what it is, which presents a problem if I'm going to a Sephardi, or non-Jewish kosher butcher, who wouldn't likely be familiar with the term.
Which part of the cow is the "kulkie"?
